[amsat-bb] Drake 2880 Unit - Rattle

["Gregory Beat" <gregory.beat@xxxxxxxxxxxx>]

Mark -

Received Drake 2880 a couple of days ago.  Noticed a "rattle" with the unit.

Opened it up and found the aluminum shield in place (screwed in place) over
the input and output stages,

BUT found 2 pieces of alumunium loose.  One is solid square ( 1" x 3/4" )
and the other piece of
metal is the same size and the shield ... but with one hole ( 3/16") and
four smaller holes (less than 1/16").

Best guess ?

Unit also had the noise figure measurements at target ( 2.5 GHz)
frequencies.  This one around 2.7 dB
